I love my dealer, great lip service. Has handled every problem I have had, my service writer knows how to take care of his customers. I will say that I deal with people who can make or brake your day. "airline employees", so I use honey instead of vinegar.
Now as for the technician that works on my car thats another story. He is either over worked or clueless. I opt for the latter
4 trips for the rear hatch rattle before I took the TSB to my writer step one ,replace the metal latch with the upgraded plastic covered one. then proceed to step two. I asked Mike, my service writer how he could have done step two and three when step 1 had not been complete. So they put the latch on and it made more noise than before, guess he thought he did not have to adjust the stops again. I did the adjustment no more rattle.
Driver side window noise, he adjusted the door, so all the lines on the door did not match, but the window did not hit the top rubber seals anymore.

I had the oil changed last week, I did an internal check on the oil level one qt low, hmmm checked the service work order they only put in 7 qts. I will go ask him about it tomorrow.

Remember if you **** them off or attack them personally and even the company you may be met with resistance.

As bob says "he who fights and runs away lives to fight another day" choose your battles carefully.

I would have never left the dealer with my car if those scratches were done to my car.

Good luck.
